Limited Slip Differential Center
ATB style differential is one of the best LSD's available. It powers both
drive wheels under all conditions. With an ordinary open differential, standard
on most cars, a lot of horse power is wasted during wheelspin under acceleration.
This happens because the open differential shifts power to the wheel with
less grip (along the path of least resistance).
The ATB differential, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel. In (drag-race) straight-line acceleration runs, this results in a close to ideal 50/50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary open differential.
During cornering, while accelerating out of a turn, the ATB differential biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed. The diff also controls loss of traction when the front wheels are on slippery surfaces such as mud, snow and ice, providing the appropriate biased traction needed to overcome these adverse conditions.
The ATB differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs. It is extremely strong and durable and since it is gear operated, it has no plates or clutches that can wear out and need costly replacement.
The differential unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. It is great for street driving or racing. Because it behaves like an open differential during ordinary driving, you will have trouble telling it's there until pushing the car to its limits.
Frequently Asked Questions
much power can the differential handle?
diff housing does the center fit?
the R180 diff bolt into a Datsun 1600 with out any mods?
A. The diff center will bolt in but the diff will need to be set up by a professional as the crown wheel to pinion gear preload needs to be set up precisely. We also recommend replacing all the bearings while the diff is apart. Fitment of the diff center and alignment by a diff specialist should cost around $150-200 not including new bearings.
oil should I use?
does the diff work?
it wear or need any maintenance?
NOTE: Center fits R180 ring gear with the 115mm carrier. 110mm carrier ring gears are common in earlier diffs. Later model diffs are recognisable by a large K cast in the top of the diff housing but its best to check the carrier size (by removing the back plate and measuring with calipers) to confirm this.
Center accepts bolt in style stub axle half shafts only. For circlip snap in style please call.
